 DETAILED DESCRIPTION
Referring to FIG. 1, a drone defense system 20 in accordance with an exemplary embodiment, and a flying drone 22 are illustrated. The drone defense system 20 is utilized to detect the flying drone 22 and to implement countermeasures to disable operation of the flying drone 22 when the flying drone 22 is within a predetermined distance of the drone defense system 20. The drone defense system 20 includes a mast assembly 40, a housing 50, a computer 58, a flying drone tracking system 54, a flying drone countermeasure system 56, a display device 70, and an electrical speaker 72.
An advantage of the drone defense system 20 is that the system 20 utilizes a mast assembly 40 which can position a flying drone countermeasure system 56 at a desired vertical height and a desired rotational position to utilize countermeasures to disable operation of the flying drone 22.
The mast assembly 40 is provided to support the other components of the drone defense system 40 and to position the housing 50 and the flying drone countermeasure system 56 therein at a desired vertical height and a desired rotational position. The mast assembly 40 includes a base member 100, a telescoping mast 102, a vertical actuator 104, and a rotational actuator 106.
The base member 100 is coupled to the ground.
The telescoping mast 102 is slidably coupled to the base member 100, and has a top portion 110 and a bottom portion 112. The bottom portion 112 extends at least partially within the base member 100. The bottom portion 112 is further operably coupled to a vertical actuator 104 which moves the telescoping mast 102 either upwardly or downwardly along the longitudinal axis 120 of the telescoping mast assembly 40. The top portion 110 of the telescoping mast 102 is coupled to the housing 50.
The vertical actuator 104 is disposed within the base member 100 and is operably coupled to the telescoping mast 102. The vertical actuator 104 moves the telescoping mast 102 (and the housing 50) upwardly in response to a control signal received from the computer 58. Alternately, the vertical actuator 104 moves the telescoping mast 102 (and the housing 50) downwardly in response to another control signal received from the computer 58. In an exemplary embodiment, the vertical actuator 104 can move the telescoping mast 102 from a first operational position (shown in dashed lines in FIG. 1) to a second operational position (shown in solid lines in FIG. 1).
The rotational actuator 106 is disposed within a top portion of the telescoping mast 102. The rotational actuator 106 is further coupled to the housing 50. The rotational actuator 106 rotates the housing 50 in a first rotational direction about the longitudinal axis 120 in response to a control signal received from the computer 58. Alternately, the rotational actuator 106 moves the housing 50 in a second rotational direction about the longitudinal axis 120 in response to another control signal from the computer 58.
The housing 50 is provided to hold the computer 58, the flying drone tracking system 54, and the flying drone countermeasure system 56 therein. The housing 50 is rotatably coupled to the top portion 110 of the telescoping mast 102.
